Hoping the community can help me out.   Have been tracking down an issue for 2 days and think I've narrowed it down to an IIS 404.2 1260 error but don't know how to fix.

First this used to work and has been working for 5+ years.   The issue started sometime in the last 30 days.   I've removed all MS updates over the last 45 days to see if that was the issue but the problem still exists.

This is on a W2K3 server with IIS 6.  In the web service extentions the following are allowed... ASP, ASP .NET v 1.1.4322, ASP .NET v2.0.50727, PHP.   All others listed are prohibited.

We have a client based application that posts and gets files from a webserver.   The clients have a unique identification account name.   The clients who used their email address as their account names are failing to get files.   They can post files with no issues.   Clients that don't have a ".com" in their account name are working fine for both post and get.

I enabled the ability to surf the directory structure via https based URLs.   Walking the directory structure gives the same results as the client based application.  Here are examples.  For the ones listed as working I am able to access the directory and view the test.log file within the directory.  

Works - https://mywebsite.com/bb/0/test@att-com/
Bad  - https://mywebsite.com/bb/0/test@att.com/
Works - https://mywebsite.com/bb/0/test@att.com_/
Works - https://mywebsite.com/bb/0/test@att.net/

For the one that is bad I get the following msg in the browswer..
       The page cannot be found
       The page you are looking for might have been removed, had its name changed, or is             temporarily unavailable.

Within the IIS logs I get the following for the working test accounts..200 0 0....

I've tried to add .com as a new web svc extension and link it to the v2.0.50727/aspnet_isapi.dll but it tells me that already exists.   Adding .com as a new mime type of text/text has no impact.

Help.   I need some ideas for how to get this working again.  

Thanks  in advance for any support!!!
